^TRIAL OF MEMA KWA VIJANA ADOLESCENT SEXUAL HEALTH INTERVENTION IN TANZANIA^

A cluster randomised trial was carried out in Mwanza Region, Tanzania to 
measure the impact of the MEMA kwa Vijana adolescent sexual health 
intervention. In this trial, 20 rural communities were grouped into three 
strata expected to have high, medium or low risk of HIV and other STIs. 
Half the communities in each stratum were randomly selected to receive the 
intervention. A cohort of students aged 14 years and over was recruited from 
primary schools in the trial communities and followed up for three years to 
measure effects on knowledge, attitudes, reported sexual behaviour, HIV 
incidence and the incidence and prevalence of other biomedical endpoints 
including STIs and pregnancy. The dataset contains data collected from male 
participants at follow-up and focuses on knowledge regarding HIV acquisition.
